Study of Bc -> BP,BV Decays with QCD Factorization

Understand

The Bc -> BP,BV decays are studied with the QCD factorization approach (where P and V denote pseudoscalar and vector mesons, respectively).

• Considering the contributions of both current-current and penguin operators, the amplitudes of branching ratios are estimated at the leading approximation.
• We find that the contributions of the penguin operators are very small due to the serious suppression by the CKM elements.
• The most promising decay modes are Bc -> Bs Pi, Bs rho, which might be easily detected at hadron colliders.
